The contact net system is an important component of the railway power supply system, and the maintenance of the contact net system faces to: the contact net system is subjected to natural environments such as wind, frost, rain, snow and the like throughout the year, and is impacted by tension and an electric bow, so that the mechanical and electrical performances of the contact net system are dynamically changed, and the main working state of the contact net system is formed under the dual functions of the machinery and the electricity. However, the current method for monitoring the overhead contact system at home and abroad comprises the following steps: 1. the manual inspection method has low efficiency, poor accuracy and slow reaction speed, consumes a great deal of labor cost and is limited by time and weather conditions; 2. the method is that the equipment is installed on special railway vehicles, such as overhead line system detection vehicles, comprehensive detection vehicles or overhead line system operation vehicles, and each department in charge of dispatching detects the overhead line system periodically or aperiodically with variable detection time interval. These two methods cannot reflect the real-time state. Therefore, it is necessary to design an online contact wire gauge.
The utility model comprises the following steps:
the present utility model aims to solve the above problems by providing an on-line contact wire gauge which solves the problems mentioned in the background art.

Preferably, the stay wire is fixedly connected with on the pillar, the one end fixedly connected with earth anchor of stay wire, the stay wire can increase the stability of pillar.
The beneficial effects of the utility model are as follows: the utility model relates to a contact line online measuring instrument, which has the characteristic of feeding back the real-time state of a line, and has the following beneficial effects compared with the traditional contact line online measuring instrument in specific use:
by additionally arranging a displacement measuring line structure on the ratchet mechanism, monitoring displacement data of contact line (carrier rope) of the contact net and on-site temperature data in real time, and when the displacement distance is not coupled with a temperature curve; when the displacement curves at the two ends are not coupled; when the displacement distance is close to the value b; possible faults and defects of the section of contact net can be early warned. When the monitored displacement value suddenly changes and is coincident with the set value, the displacement change value generated when the parts fail can judge the fault type and give off an alarm. Such as failure of the locating wire clamp, failure of the locating pipe hanging wire, failure of the locating pipe support, failure of the locating ring and the locating pipe, etc.
Description of the drawings:
for ease of illustration, the utility model is described in detail by the following detailed description and the accompanying drawings.
